Description

[Detailed Description of the Invention] This part I] 11 relates to a door hinge structure in which the door hinge of an automatic vehicle 111 is configured in a simple manner. There is a technology that moves the center of the door hinge toward the outside of the vehicle body at the initial stage of opening, and then fully opens the door around this hinge.

Technology related to this
There is a 'Ω issue. In this coffin C configuration, the small body (l111 through the first to fourth links, the door is the car 1) direction rotation movement ((
It is pivotally connected. It's Kase, the first JυIl is so cool when the door opens
, the center of the door hinge is outside the vehicle body μ (while moving in one direction,
There is a stopper mechanism that stops the function of this hinge, and another stopper mechanism that recovers the hinge mechanism when the door reaches a predetermined opening degree and stops the movement of the center of the hinge. There are 11 people.

However, in this configuration, many links and stopper mechanisms are connected in a complicated manner, which may complicate manufacturing, assembly, etc.

This invention was made in view of the above-mentioned circumstances, and an object of the present invention is to simply provide a door hinge for an automobile door IC in order to obtain a large dust fall space when the door is opened.

In order to achieve the above object, the present invention is characterized by a door being pivotally supported at the end of the folding roller (A, 1↓ is a single rotary swing roller 11 which is pivotally supported on the body side support), By guiding the door-side bale fitting piece 1C with the elongated shape formed on the support body, the rotating member and the door forcefully rotate F1 during the initial opening operation of the door!
II force is regulated and the door is rotated to the outside of the vehicle body (tilt side). This is a point that cannot be rotated relative to the member.

Embodiments of the present invention will be described below with reference to the drawings.

A door opening (2) is formed on the side surface of the ηf forest (1) of the eye movement 4f.

The front edge of this door opening (2) is formed by a part of a front pillar (3), and a door (5;) is pivotally supported on this front pillar (3) via a pair of upper and lower hinges (4).

Second best, I'll explain this sheep number (4).

The above-mentioned 70 throat pillar +3+ +c mr U-shaped support body (6) is shown in the figure. This support (6
), the longitudinal vehicle body axis (7) and the bushing T81
81, lI′1rlfi U-shaped rotating member (
9) One end is rotatably supported in the vehicle interior direction. On the other hand, an arm member t101 having a U-shaped cross section is fixed to the front edge of the door (5). The rotary end of the rotary member (9), the longitudinal door pivot and the bush (121f121),
The base of the arm member opening 0) is pivotally supported, thereby allowing the door (51) to rotate freely in the direction of the interior of the vehicle (9a) (
Reference numeral 9a) is a slider, which is fixed on the upper and lower surfaces of the rotating member (91) and comes into sliding contact with the upper and lower inner surfaces of the support (61).

The upper and lower plates of the support body (61) have a long-standing arc-shaped first kite hole O: 31 centered on the axis of the vehicle body pivot (7) and in the direction of the interior of the vehicle.

The second arc-shaped kite hole (1) centered on the door pivot (11)
An abbreviated guide hole consisting of 6) is formed.

On the other hand, the housing piece D-ra θ which is fitted into both the guide holes o: 1 and 611 is supported rotatably around the axis by the free width 1 of the arm member u01 via the roller pin 05).

1-7, when the door (5) closes the door opening (2) from the fully closed position (Fig. 1), during the initial opening operation by rotating the vehicle body (11 outward), the roller 04 moves to the first position. It is guided to the guide hole H.

As a result, free relative rotation of the rotating member (9) and the door (5;) around the door pivot (11) is restricted, and
Rotate around the door (5) or the vehicle body axis (7) to close the door axis (
111 is located on the outside of the vehicle body (1) (FIG. 2).

In the above case, when the door (5) is in the fully closed position 1δ, the roller (14
1 is the # end face of the first guide hole bar 13) and the inner surface of the rotating member (91 in the vehicle interior direction).
51 rattling is prevented. Note that the first guide hole (1
31 may be linear.

From the end of the initial 111 operations to the full opening operation (in this case (FIG. 3 1), the roller 04) engages with the second guide hole 061 and is guided in its longitudinal direction. By kneading, the free rotation of the rotating member (91) around the vehicle body axis (7) is restricted, and the rotating member (91) rotates around the door axis (11) to open the door [51'' (2). Then, when the roller circle comes into contact with the end face of the second guide hole 0 [11], the door (5) is completely opened.

When the door 15+ is closed from the fully open state in F, first, the roller 04) is guided by the second guide hole Qi'il and moves, so that the door (5) is aligned with the door axis (11).
The car body fits in one rotation (rotates to iill. Second best C,
As the roller (14) moves while being guided by the first guide hole 0J, the door (5+) rotates around the printing body pivot (7) and closes the door opening (2).

According to this invention, in the initial opening operation of the door, the door rotates around the vehicle body axis and is placed on the outside of the wind turbine body.From this position, the door pivot rotation is rotated.
The door squeaks open. Therefore, the entire door is moved away from the outer surface of the small body, and a large passing space is secured. And, in this case, the door A1 is supported by a single rotating member on the vehicle body side.

1st. The second guide hole and the mating piece fit together ((Thus, this is achieved in the first place, which simplifies the construction of the coffin, which is beneficial.
